Will,
The BookReader will serve pages of variable widths. You can see an
example here if you flip through the book and then look at a map:
http://pudl.princeton.edu/viewer.php?obj=9880vq97z#page/2/mode/2up
You need to click and hold to drag the oversized page if it bleeds off
the screen. If you simply click, the page will turn.
Take a look at the demo that comes with the BookReader distribution:
https://github.com/openlibrary/bookreader/blob/master/BookReaderDemo/BookReaderJSSimple.js
See how the br.getPageWidth and br.getPageHeight functions are hard
coded? You need to set them dynamically. In the Ethnographic Maps
example I gave above, our metadata contains the archival image
dimensions, so we use that to set the height and width before it gets
loaded. Are you using an image server? Djatoka has a metadata service
that you can query, which might be an alternative if you don't have
image dimensions.

We are using it in an edit app on the admin side of the digital libraries @ UNT.
On an expanded note. Does anyone have some success they can share in regards
to serving materials through bookreader where the contained pages of a single
item have variable widths and/or heights? Building off the demo assumes a fixed
width/height ratio, which in our experience is not always the case (consider
the book with the occasional map foldout).
In our case we do not know an image's dimensions until it has loaded so we can't
construct an array on the server side to lookup against, and doing so on page load would
charge us a significant penalty for large items (books with 1000s of pages). My current
hack has "auto" filled to the width, which breaks centering and thumbs, but
renders the odd page as legible.
So any thoughts/ideas? Thanks in advance!
Will
